ACI PRC-330-21 (IN-LB, SI) PDF Download

The ACI PRC-330-21 (IN-LB, SI) standard provides guidance and recommendations for the design and construction of concrete parking lots and site paving. It is applicable to various public facilities, commercial and retail developments, businesses, and multifamily housing projects that require parking facilities.

The standard emphasizes that while concrete slabs for parking lots share similarities with industrial pavements, streets, and highways, they also have distinct differences. Understanding and accounting for these differences is crucial in ensuring cost-effective parking lots that require minimal maintenance and provide satisfactory service for an extended period of time.

The guide covers a range of topics, including site investigation, determining slab thickness, designing joints and other details, considering durability factors, paving operations, and implementing quality-assurance procedures during construction. It also addresses maintenance and repair considerations.

It is important to note that this guide specifically focuses on the design and construction of concrete site paving for parking lots and site areas, while information related to industrial and trucking facilities can be found in ACI 330.2R.
